What does this sentence mean? The context is we are assigned a project to looking for a business case for our further study in one class. This sentence is from our syllabus but i dont understand what this one sentence mean in this case.
I don't think it's a great use of the word, but it tells me that every case must be unique. Two groups cannot study the same case, and the same case can't be studied twice, even if you're looking for different things.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
